1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - PX price is strong, supporting the PX - naphtha spread. Despite stable PTA device operation and consumption, PX cost is high and PTA profit is under pressure. However, integrated enterprises' economic benefits are improved. Polyester load is high, PTA consumption is high, and the market's willingness to buy domestic products increases. Although domestic demand weakens seasonally, polyester factories have low inventory and low willingness to cut production. The cancellation of India's BIS certification is expected to drive export growth [2] - The price of ethylene glycol lacks effective support due to high port inventory and falling coal prices. New device production increases supply pressure, but increased polyester export inquiries are expected to support downstream demand [2] 3.

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Natural Rubber - Market is in a short - term long - short stalemate. Rubber prices are expected to fluctuate within the range of 15,000 - 15,500. Supply - side support exists due to geopolitical tensions in Thailand and domestic产区停割, while demand - side growth is restricted by slow tire sales and low profits in some sectors [1]. Polyolefins - Both polyethylene and polypropylene face a situation of increasing supply and weak demand, with cost support and inventory pressure coexisting [4]. Methanol - Methanol futures are oscillating higher. The port market may be weak in the near term due to Iranian supply, while the inland market has increasing supply and demand. The 05 contract can be considered for long positions after reduced shipments [6][8]. LPG No specific overall view is provided other than presenting price, inventory, and开工率 data [12]. Pure Benzene and Styrene - Pure benzene is expected to have limited downside. The BZ2603 may oscillate between 5,300 - 5,600.

Polyester Industry Chain - PX: Rolling low - buying operations are recommended. - PTA: TA rolling low - buying and TA5 - 9 low - level positive spreads are suggested. - Ethylene Glycol: Short - term low - level oscillation is expected, and selling EG2605 - C - 4100 is advisable to obtain time value. - Short - fiber: It follows raw material fluctuations, and the disk processing fee can be shorted when it is high. - Polyester Bottle Chips: Selling PR2602 - P - 5500 is recommended, and the main disk processing fee is expected to fluctuate between 300 - 450 yuan/ton [15]. Crude Oil - The market is greatly affected by geopolitical factors. Brent crude should be monitored at the $60/barrel level. Attention should be paid to US - Russia talks, Russia - Ukraine negotiations, and the US - Venezuela situation [16]. Urea - The 2605 contract's main logic is the support of spring plowing fertilizer demand under high - supply pressure. Attention should be paid to whether the price can stabilize at 1,700 and the spirit of the urea meeting [18]. PVC and Caustic Soda - Caustic soda prices are expected to be weak. PVC supply is under pressure, demand is weak, and the price outlook is not optimistic. Short - term observation and shorting on rebounds are recommended [19]. Glass and Soda Ash - Soda ash: The supply - demand situation is bearish, and short - selling opportunities after rebounds should be noted. - Glass: The market has pressure, and the 01 contract will follow the delivery logic in December, while the 05 contract is expected to oscillate weakly at the bottom [20]. 3.

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Viewpoints - Gasoline crack spreads have declined, but PX prices are strong, supporting the PX - naphtha spread. Despite no significant fundamental changes in supply or demand, PTA plants maintain high - load operation, and PX consumption remains stable. The spread between PX and mixed xylene has widened to $120, leading Korean manufacturers to cut STDP operations and plan to shut down relevant facilities in the second half of December. PX costs are high while PTA profits are under pressure, but integrated enterprises have improved economic benefits due to self - sufficiency in raw materials. New polyester installations keep the polyester load at a high level, PTA consumption is high, and market hoarding willingness increases, causing the basis to strengthen rapidly. Although domestic demand is seasonally weak, polyester factories have low - to - medium inventory levels and low willingness to cut production. The cancellation of India's BIS certification is expected to drive export growth [2] Group 3: Summary of Key Data Price Changes - PTA spot price decreased from 4620 to 4605, a change of - 15; MEG domestic price increased from 3634 to 3667, a change of 33; PTA closing price increased from 4668 to 4684, a change of 16; MEG closing price increased from 3700 to 3758, a change of 58; 1.4D direct - spun polyester staple fiber price increased from 6325 to 6340, a change of 15; short - fiber basis decreased from 152 to 139, a change of - 13; 1 - 2 spread remained unchanged at 24; polyester staple fiber cash flow increased from 240 to 246, a change of 6; 1.4D imitation large - chemical fiber price decreased from 5300 to 5275, a change of - 25; the price difference between 1.4D direct - spun and imitation large - chemical fiber increased from 1025 to 1065, a change of 40; East China water bottle chip price increased from 5653 to 5677, a change of 24; hot - filling polyester bottle chip price increased from 5653 to 5677, a change of 24; carbonated - grade polyester bottle chip price increased from 5753 to 5777, a change of 24; outer - market water bottle chip price remained unchanged at 750; bottle - chip spot processing fee increased from 486 to 511, a change of 26; T32S pure polyester yarn price remained unchanged at 10270; T32S pure polyester yarn processing fee decreased from 3945 to 3930, a change of - 15; polyester - cotton yarn 65/35 45S price remained unchanged at 16290; cotton 328 price remained unchanged at 14715; polyester - cotton yarn profit decreased from 1534 to 1524, a change of - 10; primary three - dimensional hollow (with silicon) price remained unchanged at 7000; hollow staple fiber 6 - 15D cash flow increased from 633 to 634, a change of 2; primary low - melting - point staple fiber price decreased from 7606 to 7515, a change of - 91 [2] Market Conditions - Polyester staple fiber: The main futures of polyester staple fiber rose 26 to 6118.

Group 1: Investment Ratings - No investment ratings provided in the reports Group 2: Core Views Polyolefins (LLDPE & PP) - The fundamentals of both LLDPE and PP show a pattern of increasing supply and weakening demand, with cost support and inventory pressure coexisting. Polypropylene has high maintenance levels on the supply - side with an expected increase later, and its inventory is still higher than usual. The overall valuation is moderately low. For polyethylene, the operating load is gradually rising, and the upstream inventory is still high year - on - year [1]. Methanol - The methanol futures fluctuated upwards, with the basis being relatively firm. In the port area, Iranian gas restrictions led to multiple device shutdowns, but shipments are still fast. In the inland area, both supply and demand are increasing. It is recommended to go long on the 05 contract at low prices after the shipment decreases [4][5]. PVC & Caustic Soda - For caustic soda, the supply - demand situation still has pressure, with high inventory levels. The price is expected to be weak. For PVC, the supply pressure remains this week, and the demand is sluggish. Although there are expectations of increased exports, the overall supply - demand is in an oversupply situation, and the price is not optimistic. It is recommended to go short on PVC after a rebound [8]. Glass & Soda Ash - For soda ash, the supply - demand situation is bearish, and the price is in a downward trend. After a technical rebound, short - term long positions can be closed, and short positions can be taken after a rebound. For glass, the spot price is stable, but the demand is weakening, and the price is expected to be under pressure, with the 01 contract following the delivery logic and the 05 contract remaining weak in the short - term [9]. Polyester Industry Chain - PX may fluctuate in the range of 6600 - 7000 in the short - term and should be treated with low - buying. PTA may fluctuate in the range of 4500 - 4800 in the short - term, and low - buying and TA5 - 9 low - level positive spreads are recommended. Ethylene glycol is expected to oscillate at a low level in the short - term, and it is recommended to sell EG2605 - C - 4100 to obtain time value. Short - fiber follows the raw material fluctuations, and the processing fee on the disk should be shorted when it is high. For polyester bottle - chips, it is recommended to sell PR2602 - P - 5500 [11]. Natural Rubber - The supply - side is supported by rising overseas raw material prices due to the tense situation between Thailand and Cambodia. The demand - side has limited improvement in production capacity utilization. The market is in a short - term stalemate between long and short forces, and the rubber price is expected to oscillate in the range of 15000 - 15500 [13]. Urea - Affected by the news of India's new round of tenders, the urea price stopped falling and rebounded. The supply is abundant, and the demand is weak. The price is expected to bottom - out and rebound in the short - term, fluctuating in the range of 1650 - 1700 [15]. Crude Oil - After a rebound, the crude oil price is affected by geopolitical factors such as the situation between the US and Venezuela and the US - Russia talks. The inventory shows a slight reduction, but the supply - demand pattern is still loose. Brent crude oil should be monitored at the level of 60 dollars per barrel [16]. Pure Benzene & Styrene - For pure benzene, the short - term supply - demand is weak, but there are expectations of improvement later. It is expected to oscillate in the range of 5300 - 5600. For styrene, the supply is increasing, the demand is weak, and it is expected to oscillate in the range of 6400 - 6700 in the short - term [19]. LPG - The LPG price shows certain fluctuations.
